LOUIS .ALEXANDRE GADORET, OF PAWTUCKET, RHODE ISLAND.

BOIBIBIN-I-IOLDER.

Be it known that I, LOUIS ALEXANDRE lnnomir, a cltizen of Canada, residing at Pawtucket, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Bobbin- Holders; and I do declare the following to be a. full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in means for holding bobbins on spindles, and such invention is primarily designed for use in connection with shuttles such as those employed on looms.

The principal object of the invention is to provide a novel form of latch for holding the bobbin on the spindle in a positive man ner, so that it cannot by any chance be pulled from said spindle without releasing said latch, and to provide for releasing this latch by pushing the bobbin inwardly beyond its normal operative position, and then turning said bobbin so as to hold the latch in released position to permit the bobbin to be removed.

In the accompanying drawings forming a part of this specification and in which like numerals are employed to designate like parts throughout the same:

Figure 1 is a longitudinal sectional view of a shuttle equipped with my improved bobbin holder and spindle retaining means.

Fig. 2 is a top plan view thereof.

Fig. 3 is a. view showing the bobbin and spindle inclined, to which position they are moved preparatory to removal of the bobbin, this being the first step.

Figs. 4 and 5 are similar views showing the two remaining steps to be followed in order to remove the bobbin.

Figs. 6 and 7 are transverse sectional views taken on the lines 6-6 and 77 respectively of Fig. 1, looking in the direction of the arrows.

Fig. 8 is a view disclosing the manner in whi h the spring clip coacts with a silk tube.

Fig. 9 is a view showing the spindle and silk tube moved to an inclined position, which position these parts take in order to remove the silk tube.

In the drawings, wherein for the purpose of illustration is shown a preferred embodiment of my invention, the numeral 1 designates a shuttle of conventional form adja- Specification of Letters Patent. Patented Aug. 9, 1921.

cent one end of which a spindle 2 is pivoted the latter being provided with a slot 3, adjacent the outer end of which a spring latch;

member 4 is secured. latch projects through the slot in the spindle, and is designed to engage a shoulder. 5

The free end of this on the bobbin 6 in order to retain the latter in position onthe spindle. The shoulder 5 may be formed in any way, it being here shown in the form of a transverse slot '7 which extends through the lower end of the i bobbin and into which the latch member projects when it is in eiiective position. It it is desired, there may be any other latch arm employed, however, it is believed a sin gle latch will eii'ectively serve the purpose for which it is intended. Also, if it is desired, the lower end of the longitudinal bore of the bobbin may be reinforced by the employment of a metal sleeve 8 which is provided with slots communicating with the.

shown in Fig. 3 When in this position, the V I bobbin 6 may be grasped and forced dOWI1-, wardly toward the pivoted end of the spindle. This operation will compress the latch 7 and move it into the slot 3 of the spindle, in which position it is ineffective. Then, the bobbin may be grasped and rotated about a quarter of a turn so that the transverse slot 7 will move out of alinement with the slot 3. (In Fig. 3, the bobbin is shown after it has been rotated in the above described manner.) Since the opening 7 and the slot 3 are out of alinement and as the latch is now in efiec tive position, it will be seen that the bobbin may be moved in a reversed direction and removed trom the spindle. The bobbin may be likewise easily replaced on the spindle spindle in operative position in the shuttle.

This means is in the form of a substantially U-shaped spring metal clip 9 which is secured by a suitable fastening member 10 to the bottom of the shuttle at a point adjacent the pivoted end of the spindle, in which position it will grip the portion of the spin dle beyond the base of the bobbin. By preference, the free ends 11 of the clip are bent laterally in opposite directions to provide an effective entrance for the spindle.

The clip 9 not only serves as a means for retaining the spindle in operative position, but it also serves as a novel means for retaining a silk tube on the spindle when the latter is in operative position. Figs. 8 and 9 of the drawings l have clearly disclosed the manner in which the aforesaid clip coacts with a silk tube. By referring to these figures it will be seen that the referred to silk tube is indicated by the numeral 12, The other parts of the device including the spindle, shuttle and spindle retaining clip are designated by the same numerals employed in the already described figures and form of the invention, this being done for the sake of clearness. In order to insure a clear understanding of the manner in which the clip 9 coacts with the silk tube 12, it may be stated that in placing the silk tube on the spindle, it is forced onto the same so that its inner end is within close distance of the pivot of the spindle. Then, when the latter is swung down to operative position, the clip 9 will simultaneously grip thespindle and inner end of the tube and retain the latter in position.

A careful consideration of the foregoing description taken in conjunction with the accompanying drawings will enable persons skilled in the art to which this invention appertains to obtain a clear understanding of the construction and operation of the same, therefore, further description is deemed unnecessary.

it is to be understood that the form of the invention herein shown and described is to be taken as a preferred form of the same,

forced inwardly beyond, its normal oper-' ative position and further acting to hold said latch released when turned, permitting the bobbin to be removed.

2. In combination, a spindle having a slot, an inwardly yieldable latch arm mounted in said slot and having an abrupt shoulder spacing the inner end of the spindle and; disposed at less than an obtuse angle to said spindle, said latch arm having a cam surface converging with the spindle toward the free end of the latter, and a bobbin on said spindie having a recess at one side of its bore, said recess receiving the outer end portion of said latch arm and having an abrupt end wall abutting the aforesaid abrupt shoulder of said latch arm to positively hold the bobbin on the spindle and prevent rotation, the wall of said bore acting on said cam surface to retract the latch when said bobbin is for ed inwardly beyond its normal operative position, permitting the bobbin to be turned to dispose said latch arm out of alinement with said recess, thereby allowin removal of said bobbin. V

In testimony whereof I have hereunto set my hand.
